MACHINEFOR MAKING BAN'DAGES.

SPECIFICATION forming part of Letters Patent No. 739,267, dated September 15, 1903. Application filed October 27, 1902. Serial No. 129,021.- (No model.)

To aZZ whom it may concern,-

Be it known that I, FREDERICK L. PoHL- MANN, a citizen of the United States, residing in the city of St., Louis, in the State of Missouri, have invented certain new and useful Improvements in Machines forMaking Bandages, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a machine for use in making plaster-of-paris or other bandages; and it consists in features of novelty hereinafter fully described, and pointed out in the claims. I

Figure I is a side elevation of the machine.

1 designates the base of my machine, in which is formed a rectangular opening 2, that is occupied by a removable shallow pan 3.

To the right-hand end of the base 1, on the top thereof, is secured a pair of hinge members 4, to which is hinged a pair of ears 5, the same being formed'integral with the righthand end of a rectangular metallic frame 6, that extends over and to a point on the base 1 to the left of the removable pan 3. Formed integral with the left-hand end of the frame 6 is a vertically-arranged rectangular box 7. The side Walls 8 of this box rest directly upon the top of the base 1, and the-lower edge of the lefthand end wall 9 is cut away, so that there is a slight space between it and the top of the base 1. The lower portion of the right hand end wall 10 is cut away to form the enlarged opening 11, the same being closed or partially closed by the lower portion of a vertically-adjustable plate 12, that is arranged to slide upon the outside of said walllO and be held in vertical adjustment by means of slots 14, formed in said sliding plate.

15 designates a roller that is journaled upon a transverse shaft carried by the rec- Fig. VI is a perspective view tangular frame 6 immediately in front of the openingll and at the left-hand edge of the opening 2, occupied by the pan 3. i

Lugs 16 project from the lower side of the left-hand end wall 9, to which are pivotally connected curved arms 17, that extenddownwardly, and between the outer ends of these curvedarms is journaled a roller 18, that rests directly upon the top of the base 1.

A hopper 19 is removably positioned in thetop of the box 7.- Formed in the side walls of the box 7 are vertical slots 21, the lower The bandage-receiving roller or spindle,

which occupies a transverse position in the right-hand end of the frame 6, comprises a shaft 28, non-circularin cross-section, to the rear end of which is formed integrally a disk 29 and a trunnion 30, that occupies a suitable bearing in the side of the frame 6. The opposite end of the shaft 28 is reduced in size and squared, as indicated by 31, and is removably seated in the hub of a disk 32, with which is formed integrally a pinion 33, said pinion and disk being joined by a journal 34, that has its bearing in the front wall of the frame 6. A pinion 35 is journaled to the front side of the frame 6 and meshes with the pinion 33, and a like .pinion 36 is journaled to said frame 6 and meshes with the pinions 35 and 26.

In the operation of my machine the frame 6 and box 7 are swung upwardly on the hinges 4, and the end of the bandage to be vsaturated is wound three or four turns upon the shaft 28. The frame and box are now lowered intoposition upon the base 1 and the material, such as plaster-of-paris or medical compound,that the bandage is to be saturated with is placed into the hopper l9 and passes from thence downwardly into the box 7. The

operator now manually engages the crankhandle 37, turning the same toward the right, and in so doing the feed-roller 23 is rotated in the lower portion of the box 7 and the compound is evenly delivered and distributed onto the bandage, which is passing beneath the box 7 and being wound onto the shaft 28. The rotation of this shaft 28 is accomplished by means of the train of gearing 26, 36, 35, and The operator can regulate the flow of the compound onto the bandage by vertically adjusting the plate 12 to enlarge'or contract the opening 11 at the lower end of the wall 10. The roller 15 assists in evenly distributing the compound onto the bandage and forcing said compound through said bandage, and should there be an excess of the compound pass the roller 15 with the bandage it will drop into the removable pan 3. Thus the bandage is very thoroughly saturated and is quickly rolled upon the spindle or shaft 28. To remove the bandage from the spindle or shaft 28, the operator removes such shaft, together with the disk 32 and pinion 33, from their bearings, then disconnects the reduced end 31 of the shaft from its seat in the disk 32, and the properly prepared and rolled bandage is now slipped from the shaft 28.

I claim as my invention- 1. In a machine of the class described, a base, a framework hinged at one end of said base, a box located in said framework opposite from the hinged end thereof, in the side walls of which box are formed slots, a Winged roller operating in the lower end of said box and having its trunnions jonrnaled in the lower ends of the slots in the box, slides poone end of said bandage-receiving roller, an

integral disk and gear-wheel detachably positioned on the bandage-receiving roller opposite from the fixed disk thereof, and a train of gearing from the winged roller in the detachable wheel of the bandage receiving roller, substantially as specified.

3. In a machine of the class described, a base, apan removably positioned in said base, a framework hinged at one end of said base, a box arranged in said framework opposite the hinged end thereof, a winged deliveryroller detachably mounted for rotation in the lower end of said box, a pinion and crankhandle on one end of said delivery-roller, a pair of swinging arms pivotally secured to the outside of the box, a roller journaled between the free ends of the said swinging arms, a roller journaled transversely in the framework between the lower end of the box and the pan in the base, a bandage-receiving roller journaled for rotation in the framework at the hinged end thereof, an integral disk and pinion detachably secured to one end of the bandage-receiving roller, and a train of gearing between the pinions for simultaneonsly rotating the delivery-roller and the bandage-receiving roller, substantially as specified.
